Thanks for writing back, even to this old thread. I still think this is an interesting topic. I've continued to be interested in this subject, and in the years since the original post my understanding has evolved and I've gotten partial answers to my original questions. I eventually got...

Thanks for your reply Jonathan. I guess that like electric charges oppose gravity at the rate of 8.61E-11 C/kg. That is, if this charge density is present then the gravitational force is exactly canceled out at any distance. That is about a half million electrons per gram. So in one sense the...

Greetings, There seems to be a supposition in astronomy that charged black holes are uncommon. Is this assertion well supported? According to a paper I found by Briet and Hobill, if you look at gravitational lensing alone charged black holes look just like regular black holes, but with a mass...

Yes: I was thinking that when equal charges of opposite sign are close together they will tend to remain close and look neutral from a long way away. But when there are excess charges of the same sign they will spread out as far as possible. There is no strong force to restrain them from...

Those are great references! Thank you. They contain good hints on how to start to understand how charged particles close to a black hole might behave. Maybe I can get there eventually. I see the answer to at least one more of the things that was bothering me: If there were excess electrons...

Thanks for your reply Simon! Indeed I think it was my fuzzy thinking about the probabilities of heavier versus lighter particles going into the black hole that hung me up. I was confused by the idea of the electric field being "hidden" by the black hole and thought about it in an inconsistent...

Hi, I've been wondering about the charge balance in the known universe, factors that might alter it, and the consequences of any small imbalance that might exist. This is a sort of layman's theory. I don't expect it to be right but I'd love to understand how it can be refuted. I am surely...
